| |
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm-4.18-rc6
with top-most commit 95d6c0857e54b788982746071130d822a795026b
cpufreq: intel_pstate: Register when ACPI PCCH is present
on top of commit 9d3cce1e8b8561fed5f383d22a4d6949db4eadbe
Linux 4.18-rc5
to receive a power management fix for 4.18-rc6.
This fixes a relatively old initialization issue in intel_pstate causing the pcc-cpufreq driver to be used instead of it on some HP Proliant systems, which turned into a functional regression during the 4.17 cycle, because pcc-cpufreq is a scalability disaster and that was amplified by the idle loop rework done at that time (Rafael Wysocki).
Thanks!
